Multi Object Smooth shading by Ethan Brierley

With small changes by Dalai Felinto.

Differential Revision: https://developer.blender.org/D3213

Fix: Select all didnt' work with COW pose bones

enabled raw mesh pointer normalization

Update Flatty Light theme with topbar and minor tweaks

DRW: Fix incorrect blending function reset.

Modifier stack: move vgroup editing modifiers to new Mesh-based system.

Some notes here:
* Proximity with non-mesh objects (like curve, see TEST_2 scene in
weightvg testfile) are not working currently. This is known TODO of COW
depsgraph project.
* Proximity modifier is slower, due to some other TODO pending on
BVHTree creation/caching for Mesh.

Modifier stack: add new get_texture_coords_mesh() helper.

Will eventually fully replace get_texture_coords().

Fix ARMATURE_OT_layers_show_all now works with COW

Merge branch 'master' into blender2.8

Merge branch 'master' into blender2.8

Fix (unreported) memleak when copying object with some modifiers.

Merge branch 'master' into blender2.8

Cleanup: rename char/float conversion functions

- FTOCHAR -> unit_float_to_uchar_clamp
- F3TOCHAR3 -> unit_float_to_uchar_clamp_v3 (swap args)
- F4TOCHAR4 -> unit_float_to_uchar_clamp_v4 (swap args)
- FTOUSHORT -> unit_float_to_ushort_clamp
- USHORTTOUCHAR -> unit_ushort_to_uchar

Cleanup: move unit char/short/float to functions

This caused GCC 8.1 to crash at build time,
but was also not very nice use of macros.

added pause/resume bake functionality

works for all bake types (data, noise, mesh, particles)
